UNITED STATES NEWSWIRE SERVICES


Coastal Energy Company ("the Company") (TSX VENTURE:CEN)(AIM:CEO), an
independent exploration and production company with assets in Southeast Asia,
announced today that its wholly owned subsidiary, NuCoastal (Thailand) Limited,
has signed a Letter of Intent ("LOI") with Deep Drilling 7 Pte. Ltd. for a
three-month charter of the newbuild jackup rig "Deep Driller 7".


The rig, a Baker Marine Pacific Class 375, is currently undergoing acceptance
testing at the PPL Shipyard in Singapore and is expected to commence operations
in the Company's Songkhla field in the Gulf of Thailand by late September 2008.
The LOI allows for an extension of up to an additional three months.


Drilling capital expenditures are expected to be approximately $9 million higher
over the three month period utilizing the Deep Driller 7 rather than the
originally contracted jackup. Management believes that the incremental costs
will be largely offset by increased efficiency gains.


Randy Bartley, Chief Executive Officer of Coastal Energy commented: "We are
excited to finalize this agreement. The Deep Driller 7 will help the Company
achieve its goal of first production at Songkhla by year end."


The Company has retained the option to utilize the previously contracted rig, if
appropriate, pursuant to the amended drilling contract.

This statement contains 'forward-looking statements' as defined by the

drilling results, existence and recoverability of potential hydrocarbon
reserves, production amounts or revenues, forward capital expenditures,

(i) Per barrel of oil equivalent ("boe") amounts have been calculated using a
conversion rate of six thousand cubic feet of natural gas to one barrel of oil
equivalent (6:1). The term boe may be misleading, particularly if used in
isolation. A boe conversion ratio of 6mcf: 1bbl of oil is based upon an energy
equivalency conversion method primarily applicable at the burner tip and does
not represent a value equivalency at the wellhead.
